The Progression Bar includes the 45-52cm adjustable bar ends, which allows it to be used on any Airush 4 line kite from 4-14 meters. Together with 24m flying lines (with 10m and 14m extensions), the Progression Bar complies with IKO and BKSA teaching standards with quick and easy line changes, as well as single-line flag out safety.

Airush Bars have safety as the first priority. Industry standard Brain Quick Release and color-coding on all parts makes the Airush system perfect and hassle free for all riders. Continuing from 2018, the Low Y on the center–lines allows for a quick, single line flag out for those situations where you need it the most.
